note("c4 e4 g4 c5").sound("triangle")
I think OP's point is that the very definition of a chord is a bunch of notes played at the same time.
This might better be described as arpeggiating C#m second inversion or even C#m/G# in the right over C# in the left...
This is getting possibly-weird but you could call it an arpeggiation of G#sus4(#5)/C#
This may be a pedantic clarification, but that is the definition
In the eyes of the Common Practice two simultaneous notes are not chords; in rock they most definitely are; in EDM you don't even care, since timbre is all that matters; in jazz you'd say "it depends" (e.g. might even be a triad with an omitted 5th... depending on context!)
Music theory is too post-hoc.
